A tap for a urostomy or similar bag has a first valve member which includes a male valve element located in a cap. The cap has at least one drainage hole. A second valve member including a tubular female valve element is engageable with the male valve element to close the tap, but is disengageable from the male valve element to open the tap. Flexible and/or extendible diaphragm or sheath is secured to and encloses part of the female valve element in a fluid-tight manner and is also connected to the cap in a fluid-tight manner. The diaphragm or sheath permits relative movement between the two valve members. |
